Nerve conduction studies give doctors information about how well and how fast the nerves in your body send waves of electricity (electrical impulses). This test can be used to check for various different types of problems with the peripheral nervous system. The peripheral nervous system includes all the nerves in your body apart from those in your brain and within the spinal cord itself. Nerves in the brain and spinal cord make up the central nervous system.
